Efficient method for the solution of Maxwell’s equations for nanostructured materials [PDF]
ITM Web of Conferences, 2019 The calculation of the electromagnetic field in nanostructured materials and nano-optoelectronic devices, when the wavelength of the incident radiation is comparable with the size of the structural elements, requires the exact solution of Maxwell's ...

Generalized multiscale finite element methods for wave propagation in heterogeneous media [PDF]
, 2013 Numerical modeling of wave propagation in heterogeneous media is important in many applications. Due to the complex nature, direct numerical simulations on the fine grid are prohibitively expensive.

Nonconforming Schwarz-spectral element methods for incompressible flow [PDF]
Computers & Fluids, 2019 We present scalable implementations of spectral-element-based Schwarz overlapping (overset) methods for the incompressible Navier-Stokes (NS) equations. Our SEM-based overset grid method is implemented at the level of the NS equations, which are advanced independently within separate subdomains using interdomain velocity and pressure boundary-data ...

Mixed Mimetic Spectral Element method applied to Darcy's problem
, 2013 We present a discretization for Darcy's problem using the recently developed Mimetic Spectral Element Method. The gist lies in the exact discrete representation of integral relations.

Spectral element method for vector radiative transfer equation [PDF]
Journal of Quantitative Spectroscopy and Radiative Transfer, 2010 A spectral element method (SEM) is developed to solve polarized radiative transfer in multidimensional participating medium. The angular discretization is based on the discrete-ordinates approach, and the spatial discretization is conducted by spectral element approach. Chebyshev polynomial is used to build basis function on each element.

Edge Multiscale Methods for elliptic problems with heterogeneous coefficients
, 2018 In this paper, we proposed two new types of edge multiscale methods motivated by \cite{GL18} to solve Partial Differential Equations (PDEs) with high-contrast heterogeneous coefficients: Edge spectral multiscale Finte Element method (ESMsFEM) and Wavelet-
